Missed Period and Pregnancy Testing

A missed period is often the first sign of pregnancy, but stress, weight changes, and other conditions can also delay a period. Knowing when to take a pregnancy test helps you get an accurate result. Most home tests are most accurate from the first day of a missed period.

What Is It

Pregnancy tests detect a hormone called hCG in urine. It rises quickly in early pregnancy. Testing too early can give a false negative. Other common causes of a missed period include stress, intense exercise, weight changes, thyroid problems, polycystic ovary syndrome, and some medicines.

Symptoms

A missed or late period
Mild cramping or light spotting
Tender or swollen breasts
Nausea, with or without vomiting
Tiredness
Needing to urinate more often

Not sure what the cramping means? Mild cramping can be normal in early pregnancy. Severe or one sided pain needs care right away. Read more about pelvic pain.

Treatment

At your visit: A urine pregnancy test can confirm pregnancy. A provider can talk through other reasons for a missed period and check for warning signs. Next steps usually involve an OB or primary care provider.

At home:

Take a home test from the first day of your missed period
Use your first morning urine for the most accurate result
Retest in a few days if negative and your period has not started
Start a prenatal vitamin with folic acid if you may be pregnant

A negative test with no period after a week should be repeated or checked.
